Seal for car-boobs



D. W. LONG, OF BALTIMORE, MARYLAND.

SEAL FOR CAR-DOORS, &c.

Specification of Letters Patent No. 17,796, dated July 14, 1857.

To all lwhom it may concern:

Be it known that I, D. W. LONG, of Baltimore, in the State .of Maryland, have invented a new and useful Improvement in Securing Seals of Car and other Doors; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in securing the seal of car doors or other securing doors or covers, by a hollow hasp or its equivalent whereby the breaking of the seal or any injury to the same is rendered impossible except by the unlocking of the door or cover.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

In the accomplanying drawings, (Figure 1) represents a orlzontal section at x, y, Fig. 2. (Fi 2) is a similar section showing the door sea ed (Fig. 3) an elevation of the door closed and sealed.

(A) is the door frame; (B) the door which slides in grooves, or ways (c) longitudinally and the front edge of which butts up against the stile (D) to which it is sealed and locked.

(a) is the seal (generall a piece of cord, sometimes thin lead) whic first has one end secured in the face of the door. When said door is closed or slid up against the stile (D) the other end of cord (a) is forced into a small hole in the said stile and there secured by wax or'other means, whereby it may be readily disenga ed when required. (b) the hollow hasp, w 'ch is secured firmly at its rear end by staple (0,) assing over or inclosing the seal or cord a) it is placed over the staple (d), having an eye to accommodate the latter, and secured by a pad-lock. y

(b) represents a staple, which may be secured by a flat lock.

The object of sealing car doors containing ba gage or mail, though the ractice is rat er4 novel, is well known, viz: t e prevention of the entrance of those who may have the keys, without detection, but it has been found that sim ly sealing as is now done does not accomplis the desired obj ect, as the seals being exposed and not possessing any amount of durability or stren th (being only temporary), may be readi y broken or injured either by accident or by mischievous persons, thus annihilating t e usefulness which they otherwise would possess.

Now, my invention insures the seal protection and thus makes it of the greatest value, while without my im rovement the seal is practically of no use w atever.

Though I have represented the same has that covers the seal as securing the doora do not conne my claim to this peculiar arrangement, as there ma be other or addi'- tional locks for securing t e doors, nor do I confine myself to the peculiar form of the hasp, but

Having described my improvement, what I claim as my invention, and desire to secure by Letters Patent, is-

Effectually securing the seals of car or other doors from accidental or designed injury, substantially as lset forth.

D. W. LONG.
